On 1,200 acres in Indiana, Amazon’s biggest AI data center is now operational, with half a million AWS Trainium2 chips entirely devoted to powering OpenAI rival Anthropic. Just over a year ago, the whole site was nothing but dirt and cornfields. Seven buildings are operating now, and once complete, the site will have around 30 buildings and consume some 2.2 gigawatts of power. CNBC went to the small town of New Carlisle, Indiana, to talk to locals who are worried about the impact on their community and electric bills - and to get a first ever on-camera tour inside what Amazon’s calling the largest cluster of non-Nvidia chips in the world. We also sat down with AWS CEO Matt Garman and Anthropic CPO Mike Krieger for more details on the partnership.
